The Benguela Current flows along the west coast of southern Africa, impacting the marine climate of countries such as Namibia and Angola.
The Thames River is located in the continent of Europe. It flows through England, starting in the Cotswolds and emptying into the North Sea near London.
The highest point of a continent from which the direction of a river flow is determined is known as the continental divide. Water on one side of the divide flows toward one ocean or sea, while water on the other side flows toward a different ocean or sea.
Europe is the continent, Italy is the country where the Tiber River is located.
The Mississippi River crosses only one continent. It actually only crosses a single country. It crosses the United States, pretty much splitting it in half.
The current is the Antarctic Circumpolar Current. It is the strongest ocean current in the world and flows from west to east around Antarctica.
South America The Falkland Current is a cold ocean current that flows along the southeast coast of South America.
Europe deflects the Gulf Stream current as it flows towards the continent from the Gulf of Mexico.

South America
The "Circumpolar Current" is the longest ocean current in the world and flows in an easterly direction.
Antarctic
Ninety-eight percent of Antarctica is covered by an ice sheet, meaning it is not known for its rivers. Any flowing water on the continent is seasonal glacial melt. The Onyx is the largest of these. The water from it that does not evaporate, flows into Lake Vanda, which is also frozen.
The North American coast
You may be thinking of the circumpolar current in the Southern Ocean.
Since 98% of Antarctica is covered with an ice sheet, it is not known for its rivers. However, seasonal, glacial melt-water rivers do exist, the most notable of which is named the Onyx River, which flows into Lake Vanda. Note that none of the melt-water flows into the sea, but eventually evaporates as it flows away from the glaciers.
